All three Falcon Knights fighting alongside Ishtar are difficult to defeat due to their high stats, powerful skills, Earth Swords, and their ability to perform Triangle Attacks. The best way to defeat Meng and her sisters is to lure them into attacking the Forseti user, allowing him to defeat them on his counterattack. Unless the Forseti user in question has the Pursuit skill, he will most likely not be able to defeat them in one round. If possible, it is recommended to dispose of Meng first in order to get rid of her four leadership stars.

If Meng, Maybell, and Bleg manage to surround a unit on three sides (a triangle), they will be able to activate a Triangle Attack, which is basically a guaranteed critical hit. It is worth noting that Meng is always the one to initiate the triangle attack, although she does not utter a special battle cry when doing so.
